PAPER-RULING lVlACHlNE.

SPECIFICATION forming part of Letters Patent No. 445,518, dated January 27, 1891.

Application filed May 21, 1890- Serial No. 352,631. (No model.)

To all whom it may concern.-

Be it known that I, LUCIUS S. BIGELOW, a citizen of the United States, residing at l-Iarrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Ruling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in paper-ruling machines, the peculiarities of which will be hereinafter described and set forth.

In the accompanying drawings, forminga part of this specification, and on which like reference-lettersindicatecorrespondingparts. Figure 1 represents a side elevation of a ruling-machine of the ordinary or any approved type; Fig. 2, a plan View of a portion of the machine, showing my improvements applied thereto; and Fig. 3, a rear view of a portion of the machine, showing the driving mechanism.

The letter A designates the frame of the ordinary or any approved type, upon which the mechanism of a ruling-machine is mounted.

The letter B designates a power-pulley loosely mounted upon a shaft 0, secured to the frame. On this shaft I also mount a driving-pulleyD and a driving gear-wheel E. A sliding clutch composed of a collar G and prongs H and I is mounted on this shaft, and connected with an actuating-rod J, controlled by a hand-lever K. These instrumentalities form the subject-matter of an application filed by me, of even date herewith, for improvements in paper-ruling machines. Either this type of driving mechanism or some other form may be used as constituting this element of my improved organization. The gear-wheel E meshes with the gear=wheel L, carried by the upper feed-roller O, and through L it meshes with the gear-wheel M, carried by the lower feed-roller P, by which the paper is fed into the machine in the ordinary manner. An idler gear-wheel Q connects the gearwheel M with a pinion R on the shaft of the pen-cylinder S. Here motion is applied to the power-pulley, and it is in this manner transmitted to and through these several rollers.

The letterTdesignates a roller aboutwhich is passed one end of the lower apron, and the letter U another roller against which one part of the apron works, (and which performs other functions unnecessary to be described in connection with this invention.) The arbor of the roller U carries the pulley V, which is belted by means of a cross-belt IV with the driving-pulley D. \Vhen the particular type of driving mechanism shown is used, the feedrollers and pen-cylinder and their immediately co-operating parts are revolved, together with the rollers T and U and their immediately co-operating parts; or the latter and their parts may be operated independently of the former and their parts. This is more fully set forth in the application above referred to. It is accomplished by engaging and disengaging the prongs I with and from the gear-wheel E. A portion of the lower apron is shown at X. A shaft a, preferably mounted on the rear upper corner of the machine, carries a belt-wheel Z1 and a belt-pulley c, the latter of comparativelysmall diameter. The shaft d, also mounted upon the frame, and preferably at the lower middle portion and at one side carries a belt-wheel e and a belt-pulley f, the latter being also of relatively small diameter.

At g is represented an electrical motor of any approved style, the same being secured to the frame of the machine or floor and hav ing a fixed relation with the speed-reducing pulleys which enter into the organization of the driving mechanism. For the sake of clearness those pulleys which are immediately connected with the operating parts of the machine are termed the driving mechanism, and the other parts of the driving mechanism are called speed-reducing pulleys, which are mediately connected with the operating parts and immediately connected with the driving mechanism proper.

The motor has a pulley 71 belted by a belt 1 with the belt-wheel b. The relative size of this wheel and pulley reduces the speed of the pulley c, which is connected with the wheel I). This reduced motion is transmitted to the belt-wheel c by a belt j. A third belt serves to communicate motion from the belt-pulley f, connected with the wheel e and developingless speed, to the driving-pulley B, already referred to. It will now be seen that the organization presented admits of the use of a high-speed motor in a machine of this character, where the operative parts are driven comparatively very slowly. The speed-reducing pulleys forming a part of the organization of the driving mechanism and being a part of the equipment of the machine in regard to the construction of this part of its machinery make the machine complete when it leaves the factory for operation by a highspeed motor. Some other kind of higlrspeed motor, as a Water motor, might be used; but the electrical motor is preferred. I have illustrated and described four speedreducing wheels and pulleys. A smaller or a greater number might be employed and organized with the remainder of the driving mechanism; but this is a convenientnumber.

It will be observed that the machine as thus organized is equipped in regard to a peculiar kind of driving mechanism-to wit, a driving mechanism with speed-reducing pulleys or wheels. The motor is preferably secured to the machine so that the machine is equipped in regard to the motor also. The sizes of the pulleys or Wheels are to be determined by the proper speed to be transmitted to the several operative parts of the machine and with relation to the average velocity of high-speed motors.

On the shaft of the cylinder S are usually carried the cams for operating the pen-beam. In some cases, however, such cylinder and cams are dispensed with. In these cases the pen-cylinder and cams will not enter into the organization of the machine, and I therefore claim my improved speed-reducing mechanism Whether used with or without such cylinder and cams. I

' Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the frame of a rulin g-machine and a hi gh-speed motor mounted adjacent thereto, of a pen-cylinder and lower feed-rolls mounted on said frame, a powerpulley B and a shaft therefor on said frame, a driving-pulley D, belted to the said lower feed-rolls,a driving-gearE, geared to said pencylinder through speed-conveying gearing, a clutching device connecting the said pulley D and gear E and adapted to clutch with and unclutch from the said pulley B, and speedreducing pulleys mounted on said frame and belted together to the pulley B and to said motor.

I11 testimony whereof I affix my signature in presence of two witnesses.
